Adjusting the receiver sensitivity for the PI50 and PI60 Receiver Units
The parameter used to adjust the receiver sensitivity is the Detection Threshold (DT). This parameter is used to control the threshold level for detection of signals. The Receiver dialog box allows you to set up the detailed parameters for the signal reception.
Prerequisites
The Receiver dialog box is only available when you have set up a serial line communication with a sensor receiver.
Context
Each receiver must be able to accept and recognize the data from the gear monitoring sensors. However, sea conditions will vary, sometimes drastically. The acoustic conditions are also changing.
Procedure
1 Open the Setup menu.
2 On the Setup menu, select Installation.

Observe that the Installation dialog box opens.
3 Observe the I/O Setup page on the right side of the Installation dialog box.
Every interface is presented as a small "block diagram".
4 On the relevant serial line communication, select the receiver icon.

The Receiver dialog box opens.
5 Adjust the level of the Detection Threshold.
For the TV80 system, two different parameter ranges are used.
•  3 to 14
By increasing the parameter value, the threshold level is increased.
•  15 to 20
 By increasing the parameter value, the threshold level is decreased.
The default value for Detection Threshold (DT) is 17.
6 At the bottom of the dialog box, select Apply to save your settings.
7 Select OK to close the dialog box.
